The Different Types of Computer Software

Freeware enables computer users to do things that would otherwise be impossible or inconvenient. For example, software such as VLC video player makes it easy to play files without the need for a proprietary codec. Other useful programs include Unchecky to eliminate annoying bloatware and SpaceSniffer to easily find files eating up your hard drive.

Operating system

The operating system is the core that keeps everything else jogging; it handles how hardware and software programs interact. It is also the program that is earliest loaded into memory when your computer turns on. Other examples of program software include the basic input/output system (BIOS) and laptop language translators.

An operating system acts as the interface between a user and the computer hardware, so that application software can access the hardware only by obeying rules and procedures programmed into the OS. The operating system also provides services that simplify development and execution of application programs, such as assigning memory space and other resources, establishing priority for processes in multi-tasking systems, and loading program binary code into RAM.

It also manages input/output to and from attached hardware devices, including disk drives, printers, and dial-up ports. The operating system also sends messages to the keyboard and mouse that inform application software of what keys are being pressed, what they are clicking, and where the cursor is on screen.

Application software

Application software is computer software that allows users to carry out a specific task. It is designed to fulfil a user’s requirements and comes pre-installed on a system platform. It is usually written using a high-level programming language such as Java, C or VB. It is not possible for application software to function independently. It is also not possible for it to run on a different system platform.

The pc software you use affects how quickly your computer performs tasks. Free and open source programs often rely on shared libraries that can bog down older computers. However, this shouldn’t be a problem on newer machines with solid state drives.

Some of the most common application software includes word processors, spreadsheet programs and a variety of media players. Some application software provides support for users with special needs, such as assistive technologies for people with disabilities. Others allow users to connect with friends or colleagues over the Internet.

System software

System software is a program that manages the hardware and other aspects of the computer system. It runs in the background and performs tasks like process management, memory management, task scheduling, hardware installation, etc. System software is usually written in low-level programming languages, while application software is written in high-level languages.

Unlike application software, which is designed to accomplish specific tasks on a computer, system software provides a platform for application programs to run. It also works closely with the machine hardware and delivers high performance. Some examples of system software include operating systems, device drivers, compilers, and utility programs.

System software is often installed on a device by the manufacturer or comes preinstalled. However, it can be downloaded from the Internet as well. Application software includes word processing, web browsers, gaming applications, and other general software. It is typically written in a high-level language and uses a user interface to display the results of its work.


All hardware devices, from internal components to peripherals like a printer or keyboard, must communicate with each other for your computer to operate properly. Drivers act as an intermediary, transforming communication from software into commands that the hardware understands and executing them.

Most drivers are created by the manufacturer of a piece of hardware, though they can also be made by third-party companies that have a good reputation in the industry. Typically, driver software engineers will release updates to their products as issues arise. This may include security patches, fixes for glitches and errors, or upgrades to new technology.

Keeping your drivers updated can make a huge difference in how well your hardware performs. For example, a video card driver can improve frame rates in games or boost your printer’s speed. However, you should always download drivers from the manufacturer’s website and avoid rehosting sites that bundle bloatware, malware or extra programs with their drivers.
